Definitions

  • the present invention relates to a thickness detecting apparatus for detecting a thickness of a sheet or the like.
  • Fig. 9 is a partly sectioned front view.
  • a banknote 120 is held between a displaceable roller 110 and a stationary roller 130, and a sensor 101 is arranged above the displaceable roller 110.
  • the displaceable roller 110 is composed of a cylindrical sheath roller 111 and a core shaft 113 and an elastic body 112 made of rubber or the like and interposed between both roller 110 and core shaft 113.
  • the stationary roller 130 is composed of a roller 132 and a core shaft 131 inserted in the roller 132.
  • the displaceable roller is pressed against the stationary roller 130 by means of the elastic body 112 by a pressing force having a force center, uniformly thereover in the longitudinal direction of the roller 130.
  • the displaceable roller 110 and the stationary roller 130 are arranged in a plurality of pairs which are laid discretely in a direction widthwise of a transfer path 140 as shown in Fig. 10A which is a plan view and Fig. 10B which is a side view in order to cover the entire zone of the transfer path.
  • the width of the banknote 120 is smaller than the width of the transfer path 140, in particular, there would be caused such a case that the banknote 120 overlaps with the roller 110 only by a length which is not longer than about a half of the length of the roller as shown in Fig. 10A the displaceable roller 110 at a side end side. That is, the roller with which the banknote 120 overlaps by not longer than a half of the length thereof, would be slanted.
  • a single sensor 110 is arranged right above of the center of one of the displaceable rollers 110 as shown in Fig. 11A which is a front view.
  • Fig. 11A which is a front view.
  • foreign matter 150 such as a tape sticking to the banknote 120 passes by an end part of the displaceable roller 110, only a half of a height of the foreign matter could be detected at the center of the displaceable roller 110, resulting in a problem of difficulty in detecting the foreign matter.
  • a pair of sensors 110 are arranged respectively at opposite ends of the displaceable roller 110 as shown in Fig. 11B which is a front view, in order to improve the detection.
  • the thickness of the banknote 120 would be detected by a value which is relatively larger than its actual thickness, resulting in erroneous detection of foreign matter although no foreign matter is present. Further, should setting be made such that this situation is set so as to prevent erroneous detection of foreign matter, there would be caused problems of impossible detection of foreign matter 150 having a thickness smaller than the above-mentioned one-side lift-up and of impossible detection of concave and convex features of a banknote having a thickness which is smaller than the one-side lift-up, as shown in Fig. 12B which is a front view.
  • Fig. 13 which is a plan view
  • the displaceable roller 110 it had to be better to arrange the displaceable roller 110 at a position where the medium does not overlaps by a half, but in this case, the displaceable roller 110 should be located only at the center of the transfer path, there has be caused a problem of further decreasing a possible detection area.

  • This prior art has the features of the pre-characterising first part of claim 1 in common with the present invention. It comprises a pair of rollers, one being fixed and the other being displaceable.
  • the displaceable roller has a rubber core and a steel sheath. The sheet is fed into the nip of the rollers. Its thickness is detected from the displacement of the displaceable roller as sensed by a pair of proximity sensors arranged at both ends of the displaceable roller.
  • a thickness detecting apparatus in which a cylindrical stationary rotary body and a cylindrical displaceable rotary body are opposed to each other, for detecting a thickness of a sheet or the like in accordance with a displacement by which the displaceable rotary body is displaced from the stationary rotary body when the sheet or the like passes through between both rotary bodies, characterized in that the displaceable rotary body is formed so that a center of a load with which the displaceable rotary body presses the sheet or the like is biased in one of center-axial directions of the displaceable rotary body from the center thereof.
  • the biasing of the center of the load is effected by an elastic member interposed between a cylindrical sheathing and a core shaft of the displaceable rotary body.
  • any suitable means such as a resilient member for externally urging the displaceable rotary body toward the stationary rotary body.
  • the displaceable rotary body is composed of a cylindrical sheathing formed from a undeformable material, a shaft core inside of the former, and an elastic member therebetween, and accordingly, a center of an urging force which is applied by the elastic member and with which the inner surface of the sheathing is urged is biased from the center of the displaceable rotary body in one of center-axial directions thereof so as to bias the load center.
  • a thickness detecting apparatus which may bias a load center of a displaceable rotary body toward one side, and which is small-sized and compact so as to be inexpensive.
  • the above-mentioned elastic member may be formed in such a way that the surface of the elastic body which makes contact with the inner surface of the sheathing may be biased in one of center axial directions.
  • the urging force may be unequally biased by moldings made of one and the same material.
  • the above-mentioned elastic member may be composed of plural kinds of members having different resilient forces, and those of the elastic members having higher resilient forces may be biased in one of the center axial directions.
  • the biasing of the center of the urging force may be simply made by differences among the resilient forces of the elastic members.
  • the above-mentioned elastic member may be formed in such a configuration that a plurality of ring-like parts adapted to make contact with the inner surface of the sheathing in a ring-like manner are ununiformly arranged in the center axial direction.
  • the above-mentioned ring-like parts are arranged by uniform numbers or at ununiform positions or have ununiform diameters. Alternatively, they are arranged uniformly in the center axial direction with the combination of the aforementioned matters.
  • the elastic member is formed so as to incorporate a displacement restraining part for restraining excessive displacement toward one end part of the elastic member on a side where the urging force in the center axial direction is weaker.
  • the above-mentioned displacement restraining part is formed of such as a ring-like part having a diameter smaller than the inner diameter of the sheathing, or a ring-like part having a diameter equal to the inner diameter of the sheathing and having a weak resilient force.
  • erroneous detection may be restrained upon detection of a thickness of a sheet of the like.
